OK I formatted and reinstalled windows 8 all activated working fine. But after installing Emsisoft Internet Security Pack restarted the PC and connected to the internet but cannot access it. No pages can be displayed and I cannot connect to my LAN friends using DC++ software where we download and share stuffs with help of our net.
So which settings to do In Emsisoft IS so that I never have such problem
